Abstract (en)
Disclosed are an apparatus for automatically replacing a tungsten electrode for tungsten inert gas welding of a robot welding system and a corresponding method, wherein a gas hood mounting/ removing clamp (20) removes a gas hood from a welding gun (10) with a burnt-off tungsten electrode; a first tungsten electrode seat (41) is moved, along with a first carriage, to a position corresponding to a tungsten electrode mounting/removing clamp (60) or the welding gun (10); the tungsten electrode mounting/removing clamp (60) removes the burnt-off tungsten electrode on the welding gun (10) and rests it on the first tungsten electrode seat (41); a second tungsten electrode seat (42) is moved, along with a second carriage, to the position corresponding to the tungsten electrode mounting/removing clamp (60) or the welding gun (10); the tungsten electrode mounting/removing clamp (60) snaps a new tungsten electrode from the second tungsten electrode seat (42) and mounts it to the welding gun (10); the gas hood mounting/removing clamp (20) mounts the gas hood to the welding gun with the new tungsten electrode. The present disclosure enables automatic replacement of the tungsten electrode, which guarantees weld seam quality of robot welding, improves the automation level of the system, and enhances welding efficiency.
